The closer landscape in MLB continues to shift dramatically as the Diamondbacks face yet another injury setback, losing their closer Shelby Miller to the IL. This compounds their struggles with AJ Puk and Justin Martinez already sidelined for the season. Meanwhile, the Padres shine with two relievers making the All-Star game while the Braves' Raisel Iglesias seems to be regaining his form after a rough patch.

Josh Hader remains the top closer despite recent struggles with home runs. He notched his 25th save against the Dodgers but suffered a loss after giving up a grand slam on Tuesday. Hader’s strong season includes a commanding 63/9 K/BB ratio, keeping him firmly at the top of the closer rankings. Andrés Muñoz and Edwin Díaz follow closely, with both also enjoying impressive seasons. Muñoz has been particularly effective with a 1.06 ERA, while Díaz has allowed just one earned run since May.

Other notable performers include Aroldis Chapman, who has recorded his 20th save and extended his scoreless streak to 16 games, and Jhoan Duran, who bounced back after an illness to secure his 14th save. Meanwhile, Emmanuel Clase faced a hiccup but successfully converted his 19th save shortly after. Notably, the trade deadline looms, which could alter many closer situations across the league.
